AIR-HEATING ATTACHMENT.

Specification of Letters Patent. Patented Aug, 10, 1920,

Application'filed December 6, 1919. Serial No. 342,966.

To all whom it may concern:

Be it known that I, GEORGE D. KENNEDY, a citizen of the United States,residing at Jefferson City, in the county of Cole and State of Missouri,have invented certain new and useful Improvements in Air-HeatingAttachments, of which the following is a specifiaation, reference beinghad to the accompanying drawings.

This invention relates to certain'improvements in air heatingattachments, and it is an object of the invention to provide anattachment of this general character having novel and improved meanswhereby it may be employed with convenience and facility for heatingrooms or the like, and which is adapted to be employed in connectionwith heating units such as gas lights, oil burners, or the like. i

It is also an object of the invention to provide an attachment of thisgeneralchan acter which is adapted to be positioned above and incloseproximity to a flame, and which device includes a coil leading froma source of relatively cold air supply.

'1 he invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved airheating attachment whereby certain important advantages are attained andthe device rendered simpler, less expensive and otherwise moreconvenient and advantageous for use, as will be hereinafter more fullyset forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings:

Figure 1 is a view partly in elevation and partly in sectionillustrating an air heating attachment constructed in accordance with anembodiment of my invention and employed in connection with an oil stove;

Fig. 2 is a view in bottom plan with a portion broken away of myimproved attachment as herein disclosed; and

Fig. 3 is a view in elevation illustrating an attachment constructed inaccordance with an embodiment of my invention and employed in connectionwith a gas burner.

As is particularly illustrated in Fig. 1 of the accompanying drawings, Cdenotes a casing oi? a type generally employed in an oil stove andpositioned within said container is an oil receptacle or well It withwhich co acts in a conventional manner a burner 13. Disposed through thereceptacle or well It and the burner B is a pipe I open at its lower endso that the cold air which is generally found adjacent the floor of aroom may pass upwardly therethrough. This relatively cold air as itpasses upwardly through the pipe P and through the receptacle R servesto maintain the oil within the receptacle or well R in a cool state.

The pipe P terminates a predetermined distance above the burner B ormore particularlythe spreader S coacting with said burner and detachablycoupled with the upper end portion of said pipe, as indicated at is theend portion of a pipe 2 which is continued by the coil 3 secured to andunderlying the plate 4. l

The plate 4; as herein disclosed is substantially concavo-convex inform, and is of a size to permit its ready insertion within the casingC. The coil 3 has its inner end terminating at substantially the axial.center of the plate 4, and communicates with the opening 5 disposedthrough said plate so that the air passing through the pipe 2 and thecoil 3 will be discharged through said opening 5 above the plate 4:.

Carried by the plate 4 and overlying the opening 5 at a desired distancethereabove is a spreader plate 6 which serves to deflect the airdischarged through the opening 5 in such a manner as to materiallyincrease the heating action of said air.

By having the plate 4.- and the coil 3 carried thereby positioned abovethe burner B it will be at once self-evident that the air passingthrough the coil 8 will be heated to a comparatively high temperature,so that the heat from the burner which otherwise would be substantiallywasted is employed with advantage, as the heating qualifications of thestove will be materially increased.

I also find it of advantage to provide the plate 4 intermediate theconvolutions of the coil 3 with the openings 6 which assures a properdraft for the flame and provides for the necessary air to supportcombustion.

In the embodiment of my invention as illustrated in Fig. 3 theattachment A is substantially the same construction as has been setforth relative to my attachment as particularly illustrated in Figs. 1and 2,

except the pipe 2 extends laterally of the plate 4 and is provided witha downwardly directed extension 7 terminating in an end portion 8occupying a plane substantially parallel to the plane of the pipe 2. Theportion 8 is adapted to be secured to a lamp fixture F by the medium ofthe clamps 9 or the like. As is particularly illustrated in Fig. 3, theouter or free end of the portion 8 has coupled thereto a flexible tube Twhich may extend exterior of the building, so that the air drawn throughthe attachment'may be of a temperature equal to the temperature of theair on the outside, although if preferred the tubing T may be carried toa suitable point in close proximity to the floor.

The extension 7 as herein disclosed comprises a swivel joint 10 so thatif desired, the attachment A may be swung into an inoperative position.

From the foregoing description, it is thought to be obvious that an airheating attachment constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated, and it will alsobe obvious that my invention is susceptible of some change andmodification Without departing from theprinciples and spirit thereof,and for this reason I do not wish to be understood as limiting myself tothe precise arrangement and formation of the several parts herein shownin carrying out my invention in practice except ashereinafter claimed.

What is claimed is:

1. An air heating device comprising a plate adapted to be supportedadjacent a heating medium and provided with an opening, a coil carriedby the face of the plate opposed to the heating medium, the inner end ofthe coil being in communicationwith the opening in the plate, theopposite end of the coil being in communication with the atmosphere,said plate being provided with additional'openings arranged between theconvolutions of the, coil.

2. An air heating device comprising a plate adapted to be supportedadjacent a heating medium and provided with an opening, a conduitcarried by the face of the plate opposed to the heating medium anddischarging through the opening in the plate, said conduit being incommunication with the atmosphere, and a spreader overlying the face oftheplate remote from the heating medium, said spreader also overlyingthe opening.

3. An air heating device comprising a plate adapted to be supportedadjacent a heating medium and provided with an open.- ing, aconduitcarried by the face of the plate opposed to the heating mediumand discharging through the opening in the plate, said conduit beingv incommunication with the atmosphere, and a spreader overlying the face ofthe plate remote from the heating medium, said spreader also overlyingthe opening,'said spreader being carried by the plate.
